AVIATION MAINTENANCE ALERTS

The Aviation Maintenance Alerts provides the aviation community with an economical means to exchange service experiences and to assist the FAA in improving aeronautical product durability, reliability, and safety.  We prepare this publication from information operators and maintenance personnel who maintain civil aeronautical products pertaining to significant events or items of interest.  At the time we prepared this document, we have not fully evaluated the material.  As we identify additional facts such as cause and corrective action, we may publish additional data in subsequent issues of the Alerts.  This procedure gives Alerts’ readers prompt notice of conditions reported to the FAA Service Difficulty Reporting System (SDRS).  We welcome your participation, comments, and suggestions for improvement.  Send to:  FAA; ATTN: Aviation Data Systems Branch (AFS-620); P.O. Box 25082; Oklahoma City, OK 73125-5029.

(Editor’s notes are provided for editorial clarification and enhancement within an article. They will always be recognized as italicized words bordered by parentheses.)

 

AIRPLANES

Beechcraft:  V35A; Cut Rudder Control Tube; ATA 2720

A general aviation submitter says, "During the performance of an Annual Inspection, an IA (inspection authorization) found the right ruddervator trim control cable was routed incorrectly and had cut through the right ruddervator control tube (approximately 75%).  The tube also had signs of a crack originating from the damaged section of the tube (cut area), and had begun to bend as a result of weakening of the tube as it was being cut.  There were no maintenance entries noted in the log book to determine when this may have occurred."  (If this doesn't rate a steak dinner reward...nothing does!—Ed.)

Beechcraft:  58; Broken Nose Gear Retraction Arm; ATA 3233

"The nose gear arm (P/N 35-825172-13) failed upon extension of the landing gear on approach...," writes this mechanic.  "The pilot reported hearing a 'bang'—and could not get a nose gear 'down' indication.  After a fly-by and attempts to extend the gear, it was determined the nose gear would not come down and lock.  The pilot landed the aircraft—(and) the nose gear collapsed.  (This)  caused significant damage to the aircraft, including propeller strikes and sudden stoppages of both engines.  Actual cause of the part failure has not been determined at this time."

Cessna:  150L; Cracked Spinner Bulkhead; ATA 6113

A repair station mechanic states, "This bulkhead (P/N 0450046-5) was installed in 2007 at 1,476.4 flight hours...."  "The part has been inspected after every 100 hours of flight.  Upon the latest inspection, a crack was discovered at the base of the propeller hub.  (The hub was removed) and severe cracking was then (found), (traveling)  85% of the (distance) around the center of the bulkhead.  The spinner and the propeller remain undamaged.

"The original bulkhead from the factory lasted 5,808.7 hours before a crack began to form.  The replacement bulkhead was installed and inspected as per Cessna 150 service manual—(and) with the proper preload on the spinner."  "In my opinion:  to prevent catastrophic failure, mandatory propeller removal should take place at least every 200 hours of operation for a more thorough inspection of the bulkhead."

Cessna:  208B; Failed Oil Cooler Vernatherm; ATA 7922

"While in cruise flight," says this corporate submitter, "the pilot reported engine oil indicators showing oil pressure lower—and temperature higher than normal.  Upon removal and inspection of the engine oil cooler Vernatherm (P/N 723655), it was noted (this unit) had started to come apart due to the failure of an internal snap ring.  This caused a restriction of the engine oil cooling system, resulting in the abnormal readings.  When this Vernatherm was replaced, the engine oil parameters returned to normal."

Cessna:  337D; Frayed Flap Cables; ATA 2750

A repair station technician says, "(I) removed the L/H and R/H inboard flap extend cables from both inboard flap bell cranks to inspect for wear and damage (per information from Cessna Pilot's Association and fellow type operators during 100 hour/Annual inspection processes).  Approximately one inch behind the cable end threaded fittings on both cables I found significant broken wire strands/bundles.  Undetected, these would have led to eventual failure.  These cables were the steel type with 3,795.4 hours (original cables).  All flap cables were replaced with new, and the flap system rigged from scratch per service manual.  I suggest these cables be removed and inspected on a 500 hour minimum basis as this is becoming an issue on Skymasters fleet wide.  These cables MUST be removed from the bell crank for proper inspection; they looked fine when installed, but were obviously not airworthy."

Cessna:  550B; Sheared Flap Actuator Shaft; ATA 2752

A repair station technician states, "The flap actuator shaft (55651915) was found sheared while performing Phase One inspection task 27-51-710—Flap Motor Operational Check.  No obvious reason for this shaft to have sheared was found; no other defects were noted."

Eclipse:  EA500; Failed Aileron Joint Assembly; ATA 5751

A mechanic for a repair station begins this report with a note, "Reference Eclipse Alert Service Bulletin number 500-27-004 Rev. B:  'Aileron Joint Assembly Inspection and Replacement'.

"This service bulletin has procedures for inspecting/testing both wing's aileron joint assemblies—and replacing the aileron joint assembly whenever the aileron fails a 'friction test.'  The assembly fails testing when the bell crank is corroded and frozen in the bearing of the fitting assembly.  The attached photo has this corroded/frozen condition.  This corrosion is due to dissimilar metals.

"Since this (reference) is just a service bulletin, I suggest this inspection be upgraded to an Airworthiness Directive to prevent possible aileron malfunctions from (those aircraft) not complying with the service bulletin."

Part Total Time:  274.3 hours.

 

Piper:  PA31-350; Cracked Mail Landing Gear Trunnion; ATA 3210

"Dye penetrant inspection revealed a small crack beginning to form on the trunnion—just below the bushing area along a casting ridge," states this mechanic.  "This was the R/H aft MLG trunnion (P/N 40288000).  The aft trunnion (L/H side) is identical and is not cracked.  The forward trunnions (different P/N's) were found not to be cracked...."  "Although total part time is not known, it is assumed these parts are original equipment.  We have never replaced these on any of our other eight Navajo Chieftains."

POWERPLANTS

ECI Cylinder:  AEC631397; Cracked Cylinder; ATA 8530

"The owner who was flying the aircraft," says this mechanic, "received a warning indication (over temperature) on the third cylinder.  He made an unscheduled landing...."  "Upon inspection, (I) found a hole in the top of the cylinder adjacent to the spark plug.  I removed and replaced this cylinder with a new ECI cylinder.  The other cylinders were visually inspected—no other discrepancies were noted.

"The aircraft flew 25 more hours when the pilot complained of a bad smell in the cockpit.  I inspected the engine—a compression check noted numerous compression leaks from five remaining cylinders.  (This engine had been overhauled at 441 hours total hours; new cylinders had 404 hours on number three and 429 hours on the five remaining cylinders.)  ECI is replacing all cylinders."  (This P/N hits sixty-six times in the SDRS database—Ed.)

Part Total Time:  404.0 hours

 


ACCESSORIES

TCM Magneto: S6RSC-25P; Broken Distributor Gear Teeth; ATA 7414

A repair station technician writes, "This magneto had undergone a 500 hour inspection prior to failure of the component (approximately) 100-150 hours after the inspection.  The magneto was inspected in accordance with the TCM System Support Manual.  The magneto was opened—and the distributor gear was found with several gear teeth broken away from the gear.  The teeth were retained inside the magneto case.  No other parts were found out of place inside the magneto case.  This magneto was documented to have approximately 1000 hours total of operation."

AIR NOTES

INTERNET SERVICE DIFFICULTY REPORTING (iSDR) WEB SITE

The Federal Aviation Administration (FAA) Internet Service Difficulty Reporting (iSDR) web site is the front-end for the Service Difficulty Reporting System (SDRS) database that is maintained by the Aviation Data Systems Branch, AFS-620, in Oklahoma City, Oklahoma. The iSDR web site supports the Flight Standards Service (AFS), Service Difficulty Program by providing the aviation community with a voluntary and electronic means to conveniently submit in-service reports of failures, malfunctions, or defects on aeronautical products. The objective of the Service Difficulty Program is to achieve prompt correction of conditions adversely affecting continued airworthiness of aeronautical products. To accomplish this, Malfunction or Defect Reports (M or Ds) or Service Difficulty Reports (SDRs) as they are commonly called, are collected, converted into a common SDR format, stored, and made available to the appropriate segments of the FAA, the aviation community, and the general public for review and analysis. SDR data is accessible through the “Query SDR data” feature on the iSDR web site at: http://av-info.faa.gov/sdrx/Query.aspx.

In the past, the last two pages of the Alerts contained a paper copy of FAA Form 8010-4, Malfunction or Defect Report. To meet the requirements of *Section 508, this form will no longer be published in the Alerts; however, the form is available on the Internet at: http://forms.faa.gov/forms/faa8010‑4.pdf. You can still download and complete the form as you have in the past.

*Section 508 was enacted to eliminate barriers in information technology, to make available new opportunities for people with disabilities, and to encourage development of technologies that will help achieve these goals.

A report should be filed whenever a system, component, or part of an aircraft, powerplant, propeller, or appliance fails to function in a normal or usual manner. In addition, if a system, component, or part of an aircraft, powerplant, propeller, or appliance has a flaw or imperfection, which impairs or may impair its future function, it is considered defective and should be reported under the Service Difficulty Program.

The collection, collation, analysis of data, and the rapid dissemination of mechanical discrepancies, alerts, and trend information to the appropriate segments of the FAA and the aviation community provides an effective and economical method of ensuring future aviation safety.

The FAA analyzes SDR data for safety implications and reviews the data to identify possible trends that may not be apparent regionally or to individual operators. As a result, the FAA may disseminate safety information to a particular section of the aviation community. The FAA also may adopt new regulations or issue airworthiness directives (ADs) to address a specific problem.

The iSDR web site provides an electronic means for the general aviation community to voluntarily submit reports, and may serve as an alternative means for operators and air agencies to comply with the reporting requirements of 14 Title of the Code of Federal Regulations (CFR) Section 121.703, 125.409, 135.415, and 145.221, if accepted by their certificate-holding district office. FAA Aviation Safety Inspectors may also report service difficulty information when they conduct routine aircraft maintenance surveillance as well as accident and incident investigations.

The SDRS database contains records dating back to 1974. At the current time, we are receiving approximately 40,000 records per year. Reports may be submitted to the iSDR web site on active data entry form or submitted hardcopy to the following address.

TURBINE SECTION

ENGINEERING INVESTIGATION REPORT EIR PW100 2011-046. THE ENGINE WAS DISASSEMBLED TO INVESTIGATE THE FIRST STAGE PT BLADE FAILURE. ACCESS OF THE 1ST STAGE PT DISK REVEALED 5 OF THE 1ST STAGE PT BLADES HAD FAILED. OF THE 5 BLADES THAT FAILED, 4 WERE LOCATED CONSECUTIVELY IN THE DISK. REVIEW OF THE 1ST STAGE PT BLADE HISTORY REVEALED OF THE 4 BLADES LOCATED CONSECUTIVELY IN THE DISK, 1 ACCUMULATED 16,319.3 HRS SINCE NEW, 2 ACCUMULATED 16,901.2 HOURS SINCE NEW AND 1 ACCUMULATED 8,408.6 HRS SINCE NEW. THE 5TH BLADE ACCUMULATED 16,319.3 HRS SINCE NEW. THE SET OF BLADES WERE PN 3120983-01 WHICH IS POST SB 21419. SB 21419 BLADES HAVE AN IMPROVED PROTECTIVE COATING AS WELL AS COATING PROTECTION IN THE INTERNAL CAVITY TO PREVENT THE BLADES FROM CRACKING ABOVE THE ROOT PLATFORM. DAMAGE WHICH IS CONSIDERED SECONDARY TO THE 1ST STAGE PT BLADE FAILURE WAS THE IMPACT DAMAGE SUSTAINED BY THE FIRST STAGE PT BLADES AND ALL COMPONENTS DOWNSTREAM OF THE FIRST STAGE PT DISK. TO INVESTIGATE FOR SECONDARY DAMAGE WHICH MAY HAVE RESULTED FROM UNBALANCE ON THE PT ROTOR, THE PT SHAFT WAS ACCESSED TO DETERMINE IF INTER-SHAFT RUBBING OCCURRED - NO EVIDENCE OF INTER-SHAFT RUBBING WAS PRESENT. LAST ACCESS OF THE ENGINE WAS A REPAIR 441.5 HRS AGO FOR HP VANE DAMAGE AND BLENDING OF THE LP IMPELLER. AT THAT VISIT THE PT DISK WAS INSPECTED AS AN ASSY WITH NO DEFECTS NOTED. THE LAST ACCESS OF THE ENGINE PRIOR TO THE REPAIR WAS AN O/H 1229.6 HRS AGO. MICROSTRUCTURE ANALYSIS OF 2 HP AND 2 LP BLADES WAS CARRIED OUT TO DETERMINE WHETHER AN OVERTEMPERATURE INCIDENT OCCURRED. THE ANALYSIS DETERMINED NEITHER OF THE BLADES WERE SOLUTIONED AND THEREFORE IT WAS DETERMINED AN OVERTEMPERATURE INCIDENT DID NOT OCCUR. THE CAUSE OF THE 1ST STAGE PT BLADE FAILURE COULD NOT BE DETERMINED.

THIS DIFFERENCE COULD POSSIBLY ALLOW THE PIPE THREADED FITTING TO GO IN FURTHER AND CONTACT WITH THE BOTTOM OF THE PUMP HOUSING.
